' PIPE-WRENCH- SPEGIFIGATION forming part of Letters Patent No. 761,389,dated May 31, 1904..

Application filed August 14, 1903. Serial No. 169,468- (No model.) 7

T on whom it may concern:

Be it known that I, JAMES W. MUSKETT, a citizenof the United States,residing at Scranton, in the county of 'Lackawanna'and StateofTennsylvania, have invented new and useful Improvements inPipe-Wrenches, of which the following is a specification.

My invention relates to pipe-wrenches.

The present invention relates to that general class of.pipe-wrenchesembodying ahandle with a stationary jaw and a movable or adjustable jawconnected to the stationary .jaw

by links, and has for its object the provision of an improved and novelconstruction of great strength, durability, and simplicity adapted forrapid and easy adjustment and having the jaws self-opening.

Having the foregoing and other not specifically-mentioned objects inview, the invention embraces certain improved and novel arrangements andcombinations of parts set forth in detail hereinafter and embodied inthe appended claims.

In the accompanying drawings, Figure 1 is a side elevation showing thejaws as opened by the springs to their fullest extent; Fig. 2, a similarview showing the adjustable jaw nearly closed on the rigid jaw; Fig. 3,a section on line :12 m of Fig. "1 looking toward the fixed jaw, andFig. 4 asection on line y y of Fig. 1 looking toward the movable jaw.

The rigid or fixed jaw 1 is made integral with a handle 2, which isprovided with elongated concavities 3 on its opposite sides.

The adjustable or movable jaw 4 is located between and pivoted by a pin5 to two links 6 and 7, which in turn are pivoted to the opposite sidesof the jaw 1 by a pin 8. The two jaws and the link are provided withteeth 9.

The lower end of the adjustable jaw 4 is provided with ears 10 and 11,which are adapted to embrace opposite sides of the handle and i areturned into the concavities 3, so as to engage with the margin thereof.

Projecting from opposite sides of the jaw 1 are studs 12 and 13, whichare split and securely receive leaf-springs 1 .1.- and 15, which fromthe position shown in Fig. 1 in the direotion of the position shown inFig, 2, thereby securely grasping the pipe, and the greater the pressureon the handle the firmer will be the grip of the jaws on the pipe.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a pipe-wrench, the combination. with a stationary jaw andoperating-handle connected together, of a movable jaw having a portionthereof engaged with and guided by the handle, a link connecting themovable jaw with the stationary jaw, and a spring cooperating with thelink to open the jaws.

2. In a pipe-wrench, the combination with a stationary jaw and handleconnected thereto, of a movable jawhaving a portion thereof engaged withand guided by the handle, a link connecting said jaws to permit relativemovement thereof and a spring secured to said sta tionary jaw andbearing against said link.

3. In a pipe-wrench, the combination with a stationary jaw and a handlefor operating said jaw, of a movable jaw slidably engaged with saidhandle, a link pivotally connecting the two jaws, a stud on one of thejaws, and a leaf-spring connected to said stud and bearing against thelink.

4E. The herein-described pipe-wrench comprising a stationary jaw, ahandle connected thereto, a movable jaw having a portion slid- .ablyengagedwith the handle, links pivoted to said jaws, studs projectingfrom one of the jaws, and leaf-springs secured to said studs and engagedwith the links.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

, JAMES W. MUSKETT.
